The Chicago Tribune will launch a redesign in mid-September, Editor Ann Marie Lipinski told the staff today.

"We are committed to determining the basic architecture and sectioning of the paper within 30 days; deciding on paging (how many and where) within 45 days; understanding our staffing levels throughout the paper in 60 days; and being ready to launch a rethought and redesigned Tribune within 90 days in mid-September."

Romenesko’s got the full memo.
